Lutein is used to slow the progress of Macular Degeneration, at least that's why I use it as advised by my Optometrist. It is available over the counter in 6mg or 20mg capsules, or sometimes 10mg cap.
Here's my beef, Centrum Silver for Men contains 300mcg, that's mcg. Mcg stands for microgram. One mcg is equal to .001 mg. So Centrum Silver contains .3mg or 3/10 mg, or 3 tenths of 1 milligram - or practically just enough to be able to advertise that it's in the pill. It's not enough to make much of a difference.
Oh, by the way; the woman has blue eyes.
